Abstract
Techniques for communicating particular information from a user to a touch screen device by way of a touch event is provided. Sensors that are operatively coupled to a sensing device sense an input from the user which conveys particular information. This input is then converted by the sensing device into another signal called the sensing device signal which is then transmitted from the sensing device to the user's skin. Then a second set of sensors that are operatively coupled to a touch device receive a user-touch signal that is transmitted from the user's body. The user-touch signal is based, at least in part on the sensing device signal. The touch device then decodes the user-touch signal to determine the location of the touch event on the touch device and sensing device signal embedded in the user-touch signal to extract the particular information related to the user.
